Phenolic Composite Sandwich Panel Production Line

The phenolic composite sandwich panel production line is a specialized equipment system for producing building materials with excellent fire resistance and insulation performance. The phenolic foam core material is compounded with color steel plate, aluminum foil and other surface materials through automatic process in the phenolic panel production line to make sandwich panels widely used in building insulation, air conditioning duct and other fields.

The phenolic composite sandwich panel line is a highly integrated system, consisting of multiple functional modules working together to complete the entire production process from raw materials to finished products. As the starting point of the production line, the uncoiler system is usually equipped with multiple uncoiler machines for placing surface materials such as color steel coils, aluminum foil coils, non-woven fabric coils, etc. The coil is fixed by an inflatable shaft and a tension control device is used to ensure smooth material transportation. The uncoiler has manual centering and lateral adjustment functions, which can effectively solve the problem of coil deviation and provide accurate material supply for subsequent processes.

The double track laminating machine is the core equipment of this system, usually between 24-36 meters in length, consisting of a frame, chain plate unit, lifting unit, and insulation unit. The chain plate unit is driven by a high-precision hard tooth surface reduction motor, and the track plate undergoes stress relief and CNC machining to ensure uniform thickness of the plate. The lifting unit can be adjusted by hydraulic or servo system to accurately control the thickness of 10-200mm sheet metal. The insulation unit is heated by an electric heating tube in conjunction with a fuel furnace to maintain a process temperature of 50-70 ℃, providing optimal environmental conditions for phenolic foaming. The high-pressure foaming machine is another key equipment, equipped with a 1100L resin material tank and an 80L curing agent tank. The raw materials are transported to a high-speed mixing head at 4500r/min through a metering pump with a discharge rate of 40-120g/s, achieving precise proportioning and uniform mixing of each component.

The cutting and post-processing system is responsible for fine processing of formed sheets. The automatic tracking cutting machine adopts linear guide rails and servo drive, and achieves ± 1mm precision fixed length cutting through cylinder clamping and buffering devices. The trimming device is installed on both sides of the production line and can handle boards with a width of up to 1200mm, ensuring neat edges.

The equipment adopts a "building block" structure, which enables rapid combination of modules such as unwinding, forming, foaming, and cutting through standardized interfaces. This design not only enables the production line to be compatible with producing sandwich panels with various core materials such as PU, PIR, phenolic, and rock wool, but also allows for flexible switching of production of different products such as roof panels, wall panels, and cold storage panels according to demand. Modular design also significantly shortens the equipment delivery cycle.

The application fields of phenolic composite sandwich panel production line products are very wide. In the construction industry, it is mainly used for external wall insulation systems, cleanroom partition walls, and roof insulation.
